adapted for use with the hier block disclosed herein and also of generalapplication in connection With iiier blocks having a peripheral Wirereceiving groove.

En my application Serial No. M4554, filed Sept. 193i, there is discloseda removable foot for ilier blocks wherein the foot is attached to theblock by means of a suitable bushing or sleeve. In my application,Serial No. 554,312, tiled July 31,

931, l have disclosed an improved pre-formed iiier Wire and securingmeans therefor. The present invention is an improvement over thedisclosures oi the above mentioned applications.

An object of my invention is to provide an improved flier blocl; havinga removable foot.

Another object of my invention to provide a novel foot structure adaptedto be attached to iiier blocks o the type designed to be locked to ahobbin by inea-ns of a flange or foo-t formed on the hier block.

`Yet another object of my invention is to provide a pre-ior'ned Wireconstruction, in Which the wire itself forms, locking means whereby theiier vvire is fastened to the block.

Still ano-ther object oi my invention is the provision oi impro-ved Wireconstructions which are adapted for mutual interlocking.

With these and other objects in View, which may be incident to myimprovements, the invention consists in the parts and combinations to behereinafter set forth and claimed, with the understanding that theseveral necessary elements, comprising my invention, may be varied inconstruction, proportions and arrangement, without departing from thespirit and scope oi the appended claims.

in order to make my invention more clearly understood, 1 have shown inthe accompanying drawing means for carrying the saine into practicaleiiect, without limiting the improvements in their useful applicationsto the particular constructions, which for the purpose oi explanation,have been made the subject oi illustration.

In the drawing, like numerals refer to similar parts throughout theseveral views, of which Figure 1 is an elevational view partly invertical section of bobbin mounted upon a spindle and provided With aflier block and associated retaining bushing.

Fig. 2 is a perspective View of an improved ilier block showing theremovable foot in position on the block.

Fig. 3 is a sectional view along line 3--3 oi Fig. l.

Fig. 4 is a perspective vievv of an improved preformed Wire.

Referring to the drawing and more particularly to Fig.

mounted upc le 2, having an upper section 3, which 1s adapted to supporta freely rotataele r r block Il. The hobbin is also provided with theusual bushing 5 mounted in the opening 6 formed in the upper endthereof. The nier block 4 has a central aperture rI and is provided witha peripheral Wire receiving groove 8 into which the improved hier wire 9is iitted. The block is further provided with a peripheral groove l0adapted to receive the ioot member 1l, and is tapered at il tofacilitate positioning of the foot in the groove.

Referring to Fig. 3, the novel foot inember 11 is substantiallypear-shaped and is formed from a single piece oi Wire, shaped to conformwith the groove l0. Wire from which the foot is made may be of steel orother suitably hardened material of the character adapted to retain thedesired shape during the operation oi the flier.

The foot member is provided with an extension 12, eccentric with respectto the iiier block, adapted to engage with the bobbin bushing 5 and lockthe hier to the bobbin. In attaching the eccentric foot to the iiierblock, the vvire is sprung a sufficient amount to enable it to slip overthe end of the block, and seat in the groove l0. Since the foot memberis :formed of material which may be tensioned to give the desired springeffect, the wire will be retained in the groove during the normaloperation of the device. It will be noted that the Wire forming the footis not continuous and the ends 13, 14. may be sprung apart to enable thewire to pass over the lower end of the block. Y

While I have shown my improved eccentric foot in combination with ablock designed particularly for this type of ioot, it will be apparentthat the improved foot is adaptable for use with conventional iierblocks.

"in certain of the prior art devices, an eccentric foot formed integralwith the body of the block is used. It has also been proposed to useblocks having projections of various kinds to form a foot adapted toengage with the bobbin bushing. In these devices, during the rotation ofthe bobbin, the block oscillates or rotates and the eccentric foot bears.against the under side of the bobbin bushing and is rapidly Worn downdue to the comparatively small area oi bearing surface. Since theeccentric foot is formed integral With the body of the block, the blockmust be replaced after the foot has Worn away.

With my improved flier foot, it is possible to reclaim and use blockswhich are initially provided with an integral foot or oppositelydisposed flanges adapted for insertion into bobbins. It will beappreciated that the body of the block proper together With the Wirereceiving means i, there is disclosed a bobbin l,

is generally in condition for further use alter the eccentric foot hasWorn away.

In order to equip the discarded blocks with iny improved foot, part ofthe original eccentric ,toot or flange is cut away, leaving the body cithe block of uniform diameter. A. eripheral groove is then formed in thebody of the block near the lower end thereof, and a foot inern'oer ofthe type disclosed, iitted into the groove. blocks may then be appliedto bobbins andare in condition for further use.

It is to be noted that the eccentric ioct or ilanged foot inernber oiconventional flier blocks, is made of the saine material as the blocks,neually brass. Since the bol-coin bushings are of steel or other hardmaterial, the foot member Wears away rapidly with the resu.t the blockmust be replaced. My irnpr ved flier foot inember is made ci steel ormaterial equally as hard as the material from which the bobbin bushingis made and therefore will last longer under actual Working conditions,than the conventional brass foot. When, after a continued period of use,the foot begins to Wear, it may be readily replaced, thus effectingeconomies in maintenance oi such installations.

Referring to Fig. Ll, I have shown an improved preformed wire adaptelfor use with the hier block disclosed herein and or general applicationto flier blocks having a wire re eiving groove. The nier Wire comprisesa single piece of Wire having a drop arrn l5, and str ight arnis 16together with the usual eyelets 17 iorncd at the ends or the respectiveThe flier 'ire is provided With a central block engaging section 18adapted to it into a peripheral groove formed in the block. At eitherside oi the central block engaging sections, oiisct portions 2) areprovided. It Will be noted that these onset portions are substantiallyill-shape formation and so designed to engage with each other and loci:the wire to the block aiter the Wire is positioned in the peripheralWire receiving groove.

The manner in which the wire is attached to a :filler block is shown inFig. l. T1 e cernL l block engaging section 1S seats the groove 8 arms16 twisted or entwined so as to bring the oset portions 20 into muto.engage ent and fasten the wire to the block. y providing a preformedWire accor-ding to the present construction, it is unnecessary to usemeans other than the Wire itself to securely ias-ten the wire to theblock. 1t will be noted that when the block and Wire is in the operativeposition on a spindle, that the arms ci the vfire extend outwardly irornthe block in a direction opposite to the eccentric foot. Thisarrangement is for the purpose oi providing a balanced condition of theparts during normal operation of the device. 1n Fig. a, it will be seenthat the eccentric foot lf2, nts under the ilange of the bobbin bushing5, securely locks the nier to the bobbin.

It will be understood that the Wires may be formed with oset portions ofvarious diierent congurations and arranged for mutual engagement witheach other when the arins are in twisted relation. The basic concept ofrny invention, however, is the provision of a self-locking flier Wirewithout reference to the specific details of the oiset portions orcentral bloeit engaging section. 1t will be appreciated that While thesel" locking wire is associated with a particular forni of block, thatthe Wire can be used with other blocks having a peripheral Wirereceiving groove.
